v3.3.1 MetadataProvider, metadataURL formatting question

[Klingenstein, Nate]

Peter,

A couple things: first, you seem to have single ' quotes In your message 
for metadataURL.  I'm guessing that's not so in config or it'd probably be
screaming bloodier murder.

Anyway, have you tried a plain URL-encoded ampersand?  &

There are various other encodings you can probably use.  That error 
indicates that the above encoding is ironically available because it 
starts with an ampersand.

Take care,
Nate.

Subject: v3.3.1 MetadataProvider, metadataURL formatting question

I seem to be getting an error whenever I use a URL with an "&" in it.  The stanza I'm using in my metadata-providers.xml is as follows.

    <MetadataProvider id="docusign-provider" xsi:type="FileBackedHTTPMetadataProvider" xmlns="urn:mace:shibboleth:2.0:metadata"
        backingFile="%{idp.home}/metadata/docusign-metadata.xml"
        metadataURL='https://met.refeds.org/met/entity/https%3A//docusign.com/sp/?viewxml=true&federation=incommon-federation'
        proxyHost="proxy "
        proxyPort="3128"
        disregardTLSCertificate="false" />

The error message I am receiving is as follows.

2017-06-01 10:28:18,396 - ERROR [net.shibboleth.utilities.java.support.service.AbstractReloadableService:181] - Service 'shibboleth.MetadataResolverService': Initial load failed

Is there a way of breaking out the "&" ?  I have already tried changing the string delimeter from " to ', and also the old trick of using "\&" but with no differing results.  Or is that actually not the issue?

Thanks,
Peter
